- App1ication'fi1ed June 11,

The present invention relates to hull or burr extractors and'cleaners,one 'objectof' the invention being the provision of apparatus in whichthere is amaster unitto which 5 maybe added'auxiliary oradditional-units for operating upon the different types of picked orroughly gathered'cotton, that'is to say, since cottonis not uniformlygathered due to labor,--climatic or other conditions,

this invention iselastic in design so-thatit may beinstalledas'complete, or additional units added as desired.

A further object of the present invention is the provision of apparatusof'this type which contains'many of the essential elements of my threepatents granted April 16, 1929,being numbered 1,709,663, 1,709,714 and1,709,715 respectively, the present structure, however, being somodified as to provide for increased facilities by making provision fortwo or morecompartments for extracting hulls or' burrs from "cotton andenlarging the area for cleaningit. I v

With the foregoing and other objects in view, which will appear as thedescription proceeds, the, invention resides in the com-; bination andarrangement of parts and in the details ofconst'ruction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment ofthe'invention herein disclosed can bemade within the'scopeof what is claimed without departing from the spirit of the invention.In the accompanying drawings,

main apgin stand, the latter being shown diagrammatically; g n s Figure2is a similar view of the structure LE shown in Figure 1 with anadditional set of cleaning apparatusfor acting upon the cot-- ton;

Figure 3 is aviewsimilar to Figure 1 of an apparatus having addltiona-lhull or burr separating mechanism mounted therein' wit h a similarnumber of cleaning elements as shown in Figure 2.

Referring to the v pecially to Figure 1 thereof, the lint flue L v andgin flueF are disposed in the usual manperfor na dual office, in thatconveyor15 de; 9

The niain'casing {l which carries the present mechanism is provided withinlet 5, which has'disposed therein the two feed rolls 6 directly abovethe star roller 7, there being provided in cooperative relation withthestar rolleragrooved plate or valve 8 which is -ad-' justable to or awayfrom the star roller 7 and which is similar in construction to thatshown no in my issued Patent No. 1,7 09,7 15, but in which thestarroller 7 is preferably operated n a reverse directionyin factthe'structure so far described is similar to that shown in saidpatentg-Disposed within the casings so as to direct the cotton tobetreated-inone of two directions is a valve 9, whichwhen wide openpermits the cotton toenter the passagewayor duct 10 and there to beacted upon by cleaning rollers 11, 23 and 22, the cotton being deliveredon top of 'roller 11, to bein turndeliveredto'rollers 23 and 22, tO bereturned in reverse order over screens-L2 1, 25 and a and directedthrough'the apron or chute 12 tothe rol'lbox of gin (not shown) orothertplace of deposit, it'being'understood that the application andoperation of the invention is not confined to a gin stand. -This portionof the mechanism is employed when the cotton is burdened only with lightfield trash and hulls in suchlimited quantitythat the .usual huller ginwill idischarge them lnyorder to act upon cotton which" isexcessivelylhully, or what is known as snaps or bollys, and thus removethem from the cotton, first having been acted upon by proper adjustmentof the va'lveor plate 8 to theistar roller 7, the valve .9 is placed to:as-

jsuine the position shown in Figure. 1 -so' that I the materialisjdireotedto the left: and is acted upon by the hull extracting -mech'anism which includes the saw cylinder 14,41 spikedor' fluted stripper16-, the-brush 1 9 "and" thespikedspiralconveyors 15 and 17,"which Carlivers the'cotton' to the saw cylinder 14 trans-Y versely :of themachine and longitudinally of a the saw cylinder from each end tocenter; and conveying hulls, and remnant cotton by the Iowerorbottomside through conveyor box to its opening as in my former patentWhere the remnant cotton and hulls are deposited on spiked spiralconveyor 17, which in like manner acts upon the residue of cotton andhulls from center to each end, so that when the hulls or burrs arefinally delivered the loss of cotton is negligible. In this operation,a,considerable portion of the shale,

leaf and field trash is separated from the cotton, and goes out withthehulls into chamber C Where same is passed-from the housing 4 by theconveyor 20. or other suitable .ole vice. Thisparticular hull separatingmechanism is somewhat similar to that-shown in my issued patentsreferred 'to and is here posi tionedso that'the cotton, after beingremoved from the saw cylinder 14: by the brush 19,

will deliver it into the curvedfchute 21 and to V the cleaning rollers22,23 and 11, and from whence shale, leaf ,or' other-field trash is re-.moved. and delivered through respective screens 24, 25 and a, into'thecompartment 26 to be removed byr the conveyor 27 -or other suitabledevice. The clean cottonisthus carried upwardly by the cleaningrollers22,

; and 11 to: delivery apron orchute 12.

. As before stated, Figure 1 is the main apparatus, but to provide anadditional cleaning action' tothe cotton, the structureas illustrated inFig. 2 is desirable, the refers ence' letters primed indicatingv similarele- V ments described'forFig; 1, and in addition thereto achute orpassageway 28, instead of being curved, is inclined, and directs thetreated cotton to cleaning roller 29 by which it is'delivered to therespectiverollers '30 and 31 and thence through the chamber26 to the Vcleaning rollers 22, 23 andll and out of the apron or chute 12.-vDisposed in cooperation witl' jccleaning rollers 29, 30 and 31 arescreens 32, 33'and 3 1. Thetreatment of cotton, when diverted throughchannel-10?, is the same. in Fig, 2'as in Fig. 1, except that the cottonis carried on the topof rollers 11, 23',
